[ragel-users] (resolved?) Trouble referencing definitions from included machines (6.6)

[Austin Hastings]

Following up a little more:  I decided to try running under windows 
cmd.exe, instead of mingw. That didn't have any effect.

Frustrated, I rebuilt the ragel within mingw entirely, starting from 
"./configure".

That has apparently solved the problem. The same command line as 
described below now completes with no errors reported, and running ragel 
-V produces a .dot file that looks like what I expect.

Woo-hoo!

Can I request an option, --vis-char-transitions (defaulting to "on") to 
emit character based transitions as quoted letters instead of integer 
numbers during visualization?

That is, in the dot generator, produce something like:

1 -> 2 [ label = "'o'" ];

Instead of the current:

1 -> 2 [ label = "111" ];

(At least whenever isgraph(ch)?)

Thanks,

=Austin
